Because marine heat exchangers primarily use salt water or fresh water to cool engines in boats, they are highly susceptible to corrosion. ... If there are corroded or broken parts, we can fabricate new components. We then rebuild your heat exchanger with new gaskets and bolts.
How long do marine heat exchangers last?
Usually exhaust manifolds and risers are replaced every 3-7 years, and heat exchangers are inspected every 3-5 years.26 mar 2019

What does a heat exchanger do in a marine engine?
Heat exchangers use seawater to help the coolant side cool the engine. The coolant and the seawater pass through a series of separate tubes and the heat is transferred to keep the engine running cool and efficiently. Heat exchangers should be checked regularly for corrosion and leakage.
How long do marine oil coolers last?
As a general rule of thumb most manufacturers recommend every 3 years, although it's best to look it up in your operators manual for the specific model.26 mar 2019
How does a MerCruiser cooling system work?
MerCruiser engines may also be equipped with a closed cooling system. This cooling system is divided in two separate sub-systems: one uses seawater and the other uses coolant (called “fresh water”). The seawater system operation is similar to the standard cooling system previously described.

How do you clean a heat exchanger scale?
Add a freshwater hose to your recirculation bucket on your pump system and turn the pump back on. Continue running clean water through the heat exchanger for 10-15 minutes or until the return water runs clear. This action will also flush your pump system.9 ene 2018
What causes a heat exchanger to fail?
A common reason your heat exchanger will fail can simply be a dirty, clogged air filter. A clogged air filter restricts airflow through the furnace and overheats the heat exchanger, which eventually results in stress cracks. ... An over-sized furnace can also cause overheating and crack the heat exchanger.11 ene 2021
What are the causes of heat exchanger?
- Tube Corrosion. The biggest threat to shell and tube heat exchangers that use carbon steel tubes is oxidation (corrosion) of the heat transfer surface of its tubes. ...
- Tube Erosion. ...
- Steam or Water Hammer. ...
- Thermal Fatigue. ...
- Vibration/Resonance. ...
- Pitting of Tubes.
How do you prevent a heat exchanger from failing?
Failures due to thermal expansion of fluids are most common in steam-heated exchangers. To help prevent failure due to thermal expansion and cycling, relief valves can be installed in the heated fluid system. It also is advisable to provide some means to absorb fluid expansion.8 oct 2020
